TECHNICAL FIELD

The present disclosure relates to computing devices, and more particularly, the disclosure relates to systems and methods for communicating with media modules associated with a computing device.

BACKGROUND

Desktop computers and laptops are processing information faster and storing more information and software applications. Typically, each software application is designed as a stand alone application and does not interact with other software applications. For example, a music application accesses a file configured specifically for the music application. Other applications, such as, a photo application, cannot access the music file and the music application cannot access the photo file. A user may be overwhelmed with the multiple software applications and the various different features associated with each application.

DETAILED DESCRIPTION

Exemplary systems are first discussed with reference to the figures. Although these systems are described in detail, they are provided for purposes of illustration only and various modifications are feasible. After the exemplary systems are described, examples of flow diagrams of the systems are provided to explain the manner in which the steps of communicating with the media modules of the computing devices are provided.

FIG. 1 is a block diagram that illustrates an embodiment of a computer system 100 that is configured to communicate with media modules. The computer system 100 can include, but not limited to, a laptop computer, a desktop computer, and a server, among other computing devices. As indicated in FIG. 1, the computer system 100 comprises a processing device 110, memory 120, one or more user interface devices 130, one or more I/O devices 140, and one or more networking devices 150, each of which is connected to a local interface 160.

The processing device 110 can include any custom made or commercially available processor, a central processing unit (CPU) or an auxiliary processor among several processors associated with the laptop computer, desktop computer, and server, a semiconductor based microprocessor (in the form of a microchip), or a macroprocessor. The memory 120 can include any one or a combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, etc.)) and nonvolatile memory elements (e.g., ROM, hard drive, tape, CDROM, Flash Memory, etc.).

The one or more user interface devices 130 comprise those components with which the user (e.g., administrator) can interact with the generic computer system 100. Where the computing components of the system 100 comprise server computers or similar devices, these components can comprise those typically used in conjunction with a PC such as a keyboard and mouse.

The one or more I/O devices 140 comprise components used to facilitate connection of the computing devices of the system 100 to other devices and therefore, for instance, comprise one or more serial, parallel, small system interface (SCSI), universal serial bus (USB), or IEEE 1394 (e.g., Firewire™) connection elements. The networking devices 150 comprise the various components used to transmit and/or receive data over the network (not shown), where provided. By way of example, the networking devices 150 include a device that can communicate both inputs and outputs, for instance, a modulator/demodulator (e.g., modem), a radio frequency (RF) or infrared (IR) transceiver, a telephonic interface, a bridge, a router, as well as a network card, etc.

The memory 120 normally comprises various programs (in software and/or firmware) including an operating system (O/S) (not shown) and a menu manager 125. The O/S controls the execution of programs, including the menu manager 125, and provides scheduling, input-output control, file and data management, memory management, and communication control and related services. Operations of the menu manager 125 are described in relation to FIGS. 2-11.

FIG. 2 is a block diagram that illustrates an embodiment of a computer system, such as that shown in FIG. 1, that includes a menu manager 125 that communicates with an advanced configuration and power interface (ACPI) 235, 240 to facilitate communication with the media modules. The ACPI 235, 240 is generally an interface specification comprised of both software and hardware elements for hardware recognition, motherboard and device configuration and power management, among other functions. The computer system 200 includes a platform hardware 245 that includes, for example, a computer's architecture, operating system, and programming languages, among others. The platform hardware 245 communicates with the basic input/output system (BIOS) 250 that identifies and initiates component hardware, e.g., device driver 230 (such as, hard disk, floppy, and optical disk drives, among others) and kernel 215.

The platform hardware 245 further communicates with an ACPI content 240, which includes ACPI tables that describe the interface to the hardware. The description generally provides information that facilitates the operation and functionality of the hardware component of the computer system 200. The ACPI content 240 further includes ACPI registers that facilitate the operation of the ACPI tables as well as an ACPI BIOS, which boots the computer system 200 and implements interfaces for sleep, wake, and some restart operations.

The ACPI content 240 communicates with a menu manager 125B via an ACPI driver/AML interpreter 235. The menu manager 125B is electrically coupled to the kernel 215 that is electrically coupled to an OSPM system code 220. Alternatively or additionally, a menu manager 125A can facilitate communication between the applications 205 and kernel 215. An application 205 generally refers to a computer software that is executed by the computer system 200 and can perform certain tasks. The application 205 includes, but is not limited, to music, video, and picture applications, word processing and spreadsheet applications, and other software services, such as, Snapfish™ and Youtube™. The menu manager 125 is further described in relation to FIG. 3-11. In general, the kernel 215 connects the application 205 to the hardware of the computer system 200, such as, device driver 230, ACPI driver/AML interpreter 235, ACPI content 240, platform hardware 245, and BIOS 250.

FIG. 3 is a block diagram that illustrates an embodiment of a menu manager 125, such as that shown in FIG. 2. The menu manager 125 includes a menu system 310 that receives an input 305 from, for example, a user. The menu system 310 includes, for example, a software service that acts as the main entry point for the applications 205 (FIG. 2). The menu system 310 communicates with a customize menu 315, a search feature 320, and media modules 325A-D. The search feature 320 and the media modules 325A-D communicates with a playlist 330. The media modules 325A-D are generally software applications associated with media content, such as music, picture, and video applications. The media modules 325A-D can also include other software applications, such as, word processing and spreadsheet applications, and other software services, such as, Snapfish™ and Youtube™. The menu system 310 enables the user to perform at least one of the following:

1. Access menu functionality from within another media module 325;

2. Add and remove media modules 325A-D displayed on a display device (not shown) from a list of media modules 325A-D that can be updated via the Internet (not shown);

3. Customize a menu interface 610, 710 (FIGS. 6 and 7) via the customize menu 315 with a color scheme, background picture, transparency level and a “return to last state & resume operation” setting;

4. Search for digital media and television (Internet streamed and live) content via the search feature 320;

5. Add digital media & recorded/on-demand television content from media modules 325A-D and the search feature 320 to the playlist 330;

6. Watch the playlist 330 in full screen or in overlay windowed mode; and

7. Share the playlist 330 via upload to Snapfish™, Youtube™ or burning to Audio

CDV/VCD/DVD.

Alternatively or additionally, the menu system 310 can have the capability to display messages to the users that inform them about news relating to the media module's experiences and the availability of updates. When a user adds or removes a media module 325 from the menu interface 610, 710, the menu manager 125 can refresh the menu interface 610, 710 to reflect the change.

If a user selects a media module 325 that has not been downloaded or available to the menu manager 125, the menu system 310 can begin the download process. After the download is complete, the menu manager 125 can install the media module 325 and place a button icon associated with the downloaded media module 325 in the menu interface 610, 710, regardless of whether the user is using the software service or an application associated with menu manager 125 at the time. Alternatively or additionally, the menu manager 125 can resume an interrupted download of the media module 325. The media module 325 has, but is not limited to, at least one of the following factors:

1. Be a separate executable file or operating system;

2. Be able to add file pointers within the playlist 330 for local, network and web-based for media content;

3. When queried by the media system 310 or search feature 320, be able to output search metadata about unique digital media content offered by the feature module, e.g., metadata about on-demand Internet TV shows;

4. Be able to accept a script to load and play a local or streamed digital media file;

5. Follow the user interface design language and have different color schemes; and

6. When initialized, the medial module 325 can return to the last power state of the computer system 200 and resume operation.

The search feature 320 allows the user to search for digital media and television (e.g., Internet streamed and live) content. The digital media content can be searched from local storage, such as, the memory 120, as well as universal plug and play (UPnP) devices and Snapfish™ if the services are operational and connected. Live, recorded and Internet streamed on-demand television can also be searched using metadata and electronic programming guides (if available). The user can search for content by accessing the search feature 320 on the menu interface 610, 710.

The search feature 320 can provide a search by keywords and once the query is accepted, a search engine 322 of the search feature can “crawl” through all available offline & online storage, as well as make search requests to a television module's electronic programming guide and Internet TV content providers. As the query progresses, positive matches can be displayed to the user. If a user highlights an item found in the search result, a thumbnail of the content can be displayed. The user can either load the item or add it to the playlist 330. The menu system 310 can load the appropriate media module 325 and make a request to the media module 325 to load the media content item and begin playback. If the media module 325 is already loaded then the search feature 320 can make a request to load the media content item and begin playback.

The playlist 330 can be available from ACPI S0 power state and enables the user to add digital media and recorded/on-demand television content to the playlist 330 from any media module 325 or from the search result of the search feature 320. The playlist 330 can be stored and retrieved, viewed in full screen or as a resizable overlay-window, uploaded to Snapfish™ or YouTube™, and burned to Audio CD or Video DVD. Music, picture and video (inc. recorded television) content can be added to the playlist 330 from within media module 325 or through the search feature 320. Media can be local or from an online service. On-demand Internet television can be a link to a streaming file.

The user can access the playlist 330 by way of the menu interface 610, 710. The playlist 330 can be part of the menu system 310 or the media module 325 developed by a third party vendor. The playlist 330 can be stored locally or on removable storage. The playlist 330 can be stored in a location specific to the media module 125 and can be configured not to be changed by the user. When the user ends the session of a media module 125 and the playlist 330 has not been saved by the user exists, the user can be prompted to save the playlist 330. If the user decides not save the playlist 330 then the menu manager 125 can be configured not to store the playlist 330 to memory 120. The user can perform at least one of the following functions from within the playlist 330:

1. View current playlist 330 or load an existing playlist 330. If an existing playlist 330 is loaded, there should be the ability to return to the previous (temporary) playlist 330.

2. Scroll through list of items in current playlist 330 and see associated preview thumbnail graphics.

3. Change order of media content items in the playlist 330.

4. View the playlist 330 as a mash-up in full screen or as a resizable overlay-window.

5. Upload the playlist 330 to Snapfish™ as an album of pictures.

6. Upload the playlist 330 as a video to YouTube™.

7. Burn the playlist 330 to a Audio CD or Video DVD

The playlist 330 can be viewed in full screen mode or as a resizable overlay-window. If the user selects to watch the playlist 330 in full screen mode, the user can have the option to dynamically change to a resizable overlay-window or return to the user interface of the playlist 330. An overlay-window is generally a media player component that runs as a service on top of all applications. The overlay-window can be dynamically resized and has basic player controls, as well as a button to return to the playlist user interface or full screen playback mode.

The customize menu feature 315 enables the user to customize the interface of the media modules 325 and the menu system 310. The user can perform at least one of the following:

1. Select a new color scheme from a range of five schemes.

2. Add a background picture to the full menu user interface 610 (FIG. 6).

3. Change the transparency level of the default or custom background picture.

4. Upon pressing the button on a menu bar 615 (FIG. 6) in a new session, the user can select whether they want to go the full menu user interface 610 or to resume from the last media module 325 and media file playing.

FIG. 4 is a diagram that illustrates an embodiment of a state logic diagram in which a menu manager, such as that shown in FIG. 2, can be accessed from at least one of the ACPI power state. The interface of the menu manager 125 can be displayed in, for example, less than one second. If a user accesses the menu manager 125 from S5, S4 or S3 ACPI power states then the interface of the menu manager 125 can display the functionality available from a power state, and/or instruct the power state to change to, for example, S0 ACPI power state and load the media module 325 with the feature associated with the S0 ACPI power state. Alternatively or additionally, the search feature 320 (FIG. 3) can be available from the S0 ACPI power state to the use in menu interface 610, 710.
